Specification of Letters Patent.

Patented Mar. 1 1916.

Application filed. October 8, 1914. Serial No. 865,639.

17 b aZZ whom it may concern:

Be it known that I, PERCY J. LINDERMAN, a citizen of the United States, residing at Evanston, county of Cook, State of Illinois, have invented a certain new andusefnl Improvement in Bobbin Holders and Openers, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification. I

In filling a bobbin of the type used in tatting, the flanges at the ends of the bobbin must be held apart so as to provide room for the entrance of the cotton. This makes the filling of bobbins a slow and tedious operation.

My invention has for its object to provide a simple device into which a. bobbin may be quickly slipped and from which it may be quickly and easily removed, which shall hold the flanges of the bobbin spread apart so as to permit it to be filled easily, and which at the same time will serve as a convenient grip or handle by means of which the bobbin is supported while being filled.

The various features of novelty whereby my invention is characterized will hereinafter be pointed out with particularity in the claims; but, for a full understanding of my invention and of its object and advantages, reference may be had to the following detailed description taken in connection with the accompanying drawing, wherein Figure 1 is a top plan view of a device arranged in accordance with a preferred form of my invention; Fig. 2 is a side View of the device; Fig. 3 is a view similar to Fig. 2, showing a bobbin arranged in the holder; Fig. 4: is a section on line 4& of Fig. 1, on an enlarged scale; Fig. 5 is a section on line- 55 of Fig. l; and Fig. 6 is a view similar to Fig. 2, illustrating a modification.

Referring to Figs. 1 to 5 of the drawing, 1 represents a curved strip of metal, preferably spring metal, having at the ends thereof ears, 2 and 3, bent inwardly toward each other on the concave side of the member 1. The cars 2 and 3 may conveniently be made integral with the member 1. Each car has struck up therefrom a pocket, 4, open at the end facing the other pocket, the pockets being large enough'to receive the oppothe length of a bobbin, so that when the bobt bin, so that when the bobbin is slipped into the pockets, the pockets must be spread apart placing the member 1 under tension. Furthermore, the ears 2 and 3 will of themselves be rigid and unyielding as compared with the member 1 and consequently as the latter is flattened to permit the ears to spread apart, the outer ends of the ears drop and the inner ends rise so as to place the cars at an angle to each other, causing the flange of the bobbin which is engaged thereby to be bowed in just the opposite direction from that in which it is normally bowed and leaving a wide mouth between the two flanges of the bobbin at each end. The pockets are preferably placed at some distance from the inner ends of the ears in order that there may be in front of the mouth of each pocket a shelf or support of considerable length for engagement with the'outer face of the flange on the bobbin, thus distributing the bending stresses in the bobbin flange and avoiding the breaking off of the sharp points or tips on the flanges. At the inner end of each car there may be a curved extension, 7 extending downwardly and inwardly toward the member 1, the convex sides of these two extensions being toward each other. These extensions form finger pieces adapted to be grasped between two of the fingers of one hand for the purpose of holding the bobbin while it is being filled and at the same time preventing the bobbin from accidentally slipping out of the device. It will be seen that after the bobbin is slipped into the holder, it is held in its open condition until it is intentionally removed, because the grip of the holder upon the bobbin is such that the holder may be laid aside without additional danger that the bobbin will drop out or even become loose or mislaid.

In Fig. 6 I have illustrated a slight modification in which, instead of the finger pieces 7, I have provided the bow-shaped member 10, corresponding to the member 1, with a handle, 11. This may conveniently be accomplished by making the member 10 long enough to permit the middle portion thereof to be bent into aloop, as illustrated, this loop permitting the ears 2 and 3 to be sprung apart and, when grasped in the hand, preventing them from releasing the bobbin.

While I have illustrated and described with particularity only a single preferred form of my invention with a slight modification, 1 do not desire to be limited to the eXact structural details thus illustrated and described; but'intend to cover all forms and arrangements which come within the terms employed in the definitions of my invention constituting the appended claims.

I claim:

1. A bobbin opener and holder comprising a bowed spring member having at the ends thereof devices for engaging with the opposite ends of one of the flanges of a bobbin.

2. A bobbin opener and holder comprising a bowed spring member having at the ends thereof devices for engaging with the opposite ends of one of the flan es of a bobbin,

said devices being spaced apart a distance less than the length of said flange.

3. A bobbin-opener and holder comprising devices for engaging with opposite ends of one of the flanges of a bobbin, and means for connecting said devices yieldingly toing a bowed spring member having the ends bent inwardly toward each other and then downwardly to form finger pieces, and means .on said ends above the fingerpieces for receiving the ends of one of the flanges of a bobbin.

6. In a device of the class described, the combination of a backing piece having a handle forming a loop at about its midsection, by means of which the backing piece may be extended and anupturned portion at each end of the backing piece having perforations' therein adapted to receive the lower lips of the bobbin, the said perforations being in such relation to the backing piece, that when the bobbin is in position on the backing piece the lips of the bobbin are sprung apart and the bobbin frictioned against the backing piece.

In testimonywhereof, I sign th1sspecification in the presence of two witnesses.
